Answer 1

4. Cell-mediated immunity and humoral immunity are the two types of immune responses produced by the body on encounter with pathogen.

Cell-mediated immunity	Humoral immunity
This type of immunity is provided by T-cells.	This type of immunity is provided by antibodies secreted by B-cells.
It shows delayed response to antigens.	It is rapid in response to antigen.
It involves T-helper cells, T-cytotoxic cells and cytokines.	It involves antibodies with T-helper cells.
It is mainly active against endogenous or intracellular antigens.	It is active against exogenous or extracellular antigens.
Soluble-products called cytokines released due to cell-to-cell contact on encounter with pathogen, which act against antigens.	Antibodies circulate in the serum and act against antigens.
